Siemens A6X30142397 Red Pushbutton Switch
Catalog comparison
The Siemens A6X30142397 is a round, non-illuminated pushbutton configured as SPST-NC (normally closed), rated 10A AC/DC, with front panel mounting. Its IP66/IP67/IP69K environmental rating and 10-million-cycle mechanical/electrical life place it in heavy-duty industrial operator-interface applications.
This page compares the primary A6X30142397 against in-catalog parts sharing the same series or MPN prefix grouping. All comparison rows are parametric similarities only — none represent OEM-endorsed interchange approval. Readers must perform their own qualification.

Why A6X30143907 is similar
A6X30143907 (Extended Stroke variant) shares the same MPN prefix length (7 characters) and the red, round, non-illuminated pushbutton actuation type under the 3SU1 series. It differs by panel cutout requirement (22.3mm) and carries no published IP rating or contact configuration — indicating it is a body/actuator subassembly requiring separate contact blocks.
Why A6X30140393 is similar
A6X30140393 aligns on 3SU1 series membership, 22.3mm round panel cutout, and pushbutton, round actuator type. It differs by offering illuminated actuation and a white lens — adding illumination source and contact block requirements not present in the primary part's fully assembled form factor.
Why A6X30140307 is similar
A6X30140307 shares the Siemens brand, box packaging, and MPN prefix length, but represents a different operator type (selector, O-I) with a 30.5mm panel cutout. This indicates a larger-format 30mm family member rather than a drop-in replacement for the A6X30142397.

Integration notes
The A6X30142397 arrives as a complete assembled operator device — no separate contact block or lamp source required to achieve its SPST-NC function. Its IP66/IP67/IP69K rating supports high-pressure washdown and temporary submersion, making it suitable for food-processing, pharmaceutical, and outdoor enclosure applications where chemical resistance or cyclic humidity is expected.
The front-panel mounting orientation and operating temperature window (25°C to 70°C) should be confirmed against the target enclosure's thermal profile during layout planning.
Engineering verification checklist
- Circuit type (SPST-NC) matches the safety function requirement
- Current rating (10A AC/DC) suits the controlled load
- Mechanical and electrical life cycles align with expected actuation frequency
- IP66/IP67/IP69K rating is compatible with the installation environment
- Panel cutout and mounting depth accommodate the device
- Operating temperature range (25°C to 70°C) is appropriate for the enclosure conditions
- Actuator color (red) is correct for the designated function (e.g., emergency-stop identification if applicable)
FAQ
What is the contact arrangement of the A6X30142397? The device is configured SPST-NC (single-pole, single-throw, normally closed), meaning the circuit is closed in the unactuated state and opens when the button is pressed.
Does the A6X30142397 require separate contact blocks or illumination sources? No — this is a fully assembled pushbutton operator with the contact function integrated; no additional contact blocks or lamp sources are required for basic SPST-NC operation.
What environmental conditions does the A6X30142397 tolerate? The part carries an IP66/IP67/IP69K rating (dust-tight, water-resistant, and waterproof against high-pressure washdown and temporary immersion) and operates across 25°C to 70°C.
